|
are fully understood and met. |
|
|
|
|
|
|
Caution |
|
A caution calls attention to a procedure, practice or the like which, if not |
|
|
correctly performed or adhered to, could result in damage to or the |

|
|
|
|
Personal Safety Considerations |
|
|
|
WARNING |
|
This is a Safety Class I product (provided with a protective earthing |
|
|
ground incorporated in the power cord). The mains plug shall only be |
|
|
inserted in a socket outlet provided with a protective earth contact. Any |
|
|
interruption of the protective conductor, inside or outside the |
|
|
instrument, is likely to make the instrument dangerous. Intentional |
|
|
interruption is prohibited. |
|
|
If this instrument is not used as specified, the protection provided by the |
|
|
equipment could be impaired. This instrument must be used in a normal |
|
|
condition (in which all means of protection are intact) only. |
|
|
No operator serviceable parts inside. Refer servicing to qualified |
|
|
personnel. To prevent electrical shock, do not remove covers. |
|
|
For continued protection against fire hazard, replace the line fuse(s) |
|
|
only with fuses of the same type and rating (for example, normal blow, |
|
|
time delay, etc.). The use of other fuses or material is prohibited. |

General Safety Considerations |
|
|
WARNING |
Before this instrument is switched on, make sure it has been properly |
|
grounded through the protective conductor of the ac power cable to a |
|
socket outlet provided with protective earth contact. |
|
Any interruption of the protective (grounding) conductor, inside or |
|
outside the instrument, or disconnection of the protective earth terminal |
|
can result in personal injury. |
|
|
|
|
Caution |
Any adjustments or service procedures that require operation of the |
|
instrument with protective covers removed should be performed only by |
|
trained service personnel. |
|
|
|
Markings |
|
The CE mark shows that the product complies with all the |
|
relevant European legal Directives (if accompanied by a |
|
year, it signifies when the design was proven. |
Group 1
ISM Class A
This is the symbol of an Industrial Scientific and Medical Group 1 Class A product.
The CSA mark is a registered trademark of the Canadian Standards Association.
External Protective Earth Terminal.
While this is a Class I product, provided with a protective earthing conductor in a power cord, an external protective earthing terminal has also been provided. This terminal is for use where the earthing cannot be assured. At least an 18AWG earthing conductor should be used in such an instance, to ground the instrument to an assured earth terminal.

Returning Your Power Meter for Service
Use the information in this section if you need to return your power meter to Agilent Technologies.
Package the Power Meter for Shipment
Use the following steps to package the power meter for shipment to Agilent Technologies for service:
1.Fill in a blue service tag (available at the end of this guide) and attach it to the power meter. Please be as specific as possible about the nature of the problem. Send a copy of any or all of the following information:
n
n
Any error messages that appeared on the power meter display.
Any information on the performance of the power meter.
Caution |
Power meter damage can result from using packaging materials other than |
|
|
those specified. Never use styrene pellets in any shape as packaging |
|
|
materials. They do not adequately cushion the power meter or prevent it |
|
|
from shifting in the carton. Styrene pellets cause power meter damage by |
|
|
generating static electricity and by lodging in the rear panel. |
|
|
|
|
|
2. |
Use the original packaging materials or a strong shipping container that is |
|
|
made of double-walled, corrugated cardboard with 159 kg (350 lb) bursting |
|
|
strength. The carton must be both large enough and strong enough to |
|
|
accommodate the power meter and allow at least 3 to 4 inches on all sides of |
|
|
the power meter for packing material. |
|
3. |
Surround the power meter with at least 3 to 4 inches of packing material, or |
|
|
enough to prevent the power meter from moving in the carton. If packing |
|
|
foam is not available, the best alternative is SD-240 Air Cap TM from Sealed |
|
|
Air Corporation (Commerce, CA 90001). Air Cap looks like a plastic sheet |
|
|
covered with 1-1/4 inch air filled bubbles. Use the pink Air Cap to reduce |
|
|
static electricity. Wrap the power meter several times in the material to both |
|
|
protect the power meter and prevent it from moving in the carton. |
|
4. |
Seal the shipping container securely with strong nylon adhesive tape. |
|
5. |
Mark the shipping container “FRAGILE, HANDLE WITH CARE” to |
|
|
ensure careful handling. |
|
6. |
Retain copies of all shipping papers. |

Introduction
Introduction
This chapter details the power meter’s specifications and supplemental characteristics.
Specifications describe the warranted performance and apply after a 30 minute warm-up. These specifications are valid over the power meter’s operating and environmental range unless otherwise stated and after performing a zero and calibration.
Supplemental characteristics, which are shown in italics, are intended to provide information useful in applying the power meter by giving typical, but non-warranted performance parameters. These characteristics are shown in italics or denoted as “typical”, “nominal” or “approximate”.
For information on measurement uncertainty calculations, refer to Agilent Application Note 64-1A, “Fundamentals of RF and Microwave Power Measurements”, Literature Number 5965-6630.

Measurement Speed
Over the GP-IB, three measurement speed modes are available as shown, along with the typical maximum measurement speed for each mode:
•Normal: 20 readings/second
•x2: 40 readings/second
•Fast: 200 readings/second, for Agilent E-series power sensors only
Maximum measurement speed is obtained using binary output in free run trigger mode.
Zero Drift of Sensors
Power sensor dependent (refer to Table 1-3).

Measurement Noise
Power sensor dependent (refer to Table 1-2 and Table 1-3).
Averaging effects on measurement noise. Averaging over 1 to 1024 readings is available for reducing noise. Table 1-3 provides the measurement noise for a particular power sensor with the number of averages set to 16 for normal mode and 32 for x2 mode. Use the “Noise Multiplier” for the appropriate mode (normal or x2) and number of averages to determine the total measurement noise value.
For example, for an Agilent 8481D power sensor in normal mode with the number of averages set to 4, the measurement noise is equal to:
(<45 pW x 2.75) = <124 pW

For Agilent E-series power sensors
In FAST mode, within the range -50 dBm to +17 dBm, for a 10 dB decreasing power step, the settling time is 10 ms1 for the Agilent E4418B and 20 ms1 for the Agilent E4419B
1When a decreasing power step crosses the power sensor’s auto-range switch point, add 25 ms. Refer to the relevant power sensor manual for further information.
For Agilent E-series power sensors in normal and x2 speed modes, manual filter, 10 dB decreasing power step:

Power Sensor Specifications
Definitions
Zero Set
In any power measurement, the power meter must initially be set to zero with no power applied to the power sensor. Zero setting is accomplished within the power meter by digitally correcting for residual offsets.
Zero Drift
This parameter is also called long term stability and is the change in the power meter indication over a long time (usually one hour) for a constant input power at a constant temperature, after a defined warm-up interval.
Measurement Noise
This parameter is also known as short term stability and is specified as the change in the power meter indication over a short time interval (usually one minute) for a constant input power at a constant temperature.
